Document Summary

Antidepressants (selective serotonin-reuptake inhibitors) are the overwhelming treatment for depression. Stem from how they affect certain brain circuits and the chemicals (called neurotransmitters) that pass along signals from one nerve cell to another in the brain. Process in which neurotransmitters are naturally absorbed back into the nerve cells in the brain. Reuptake inhibitors prevents this from happening neurotransmitter stays at least temporarily in the gap between nerves (synapse) Keeping levels of the neurotransmitters higher could improve communication between nerve cells. That can strengthen circuits to the brain which regulate mood. Antidepressant use in canada: among the highest in the world. As much as 9% of our population is on an antidepressant drug. Canada is the third highest among antidepressant use (among 23 developed countries) (behind. Study: role of translocator protein density, a marker of neuroinflammation, in the brain during major.
